STEM WINDING AND SETTING DEVICE FOR WATCHES.

Specification of Letters Patent.

Patented July 4, 1916.

Application filed March 8, 1916. Serial No. 82,801.

To all whom it may concern:

Be it known that I, SOLOMON MALLIN, a subject of the Czar of Russia,residing at Pittsburgh, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements in StemWinding and Setting Devices for Watches, of which the following is aspecification.

This invention relates to stem winding and setting devices for watches,particularly adapted for use in connection with the cheap grade of watchnow sold at small expense, although the device is adapted to any form ofWatch wherein it is found applicable, and the invention has for itsprimary object to provide a device of such class, with means in a manneras hereinafter set forth, to overcome the necessity of shifting the stemin and holding it in when winding the watch as is the practice now ingeneral vogue in connection with the popular price watches now on themarket.

Further objects of the invention are to provide a stem winding andsetting device for watches, capable of being attached to the cheap gradeof watch now in general use without changing or rearranging any of theparts of the watch mechanism under such conditions providing for theemployment of the device in accordance with this invention withoutincreasing to any material extent the expense of manufacturing the cheapade of watch now in general use.

Further objects of the invention are to provide a stem winding andsetting device for Watches which is simple in its construction andarrangement, strong, durable, efficient and convenient in its use, andinexpensive.

With the foregoing and other Objects in view the invention consists ofthe novel construction, combination and arrangement of parts ashereinafter more specifically described and illustrated in theaccompanying drawings, wherein is shown an embodiment of the invention,but it is to be understood that changes, variations and modificationscan be resorted to which come within the scope of the claims hereuntoappended.

In the drawings wherein like reference characters denote correspondingparts throughout the several views :Figure 1 is a rear elevation of awatch mechanism, broken away, showing the adaptation therewith ofcertain of the elements of the stem winding and setting device inaccordance with this invention. Fig. 2 is a rear elevation of a portionof the watch mechanism showing the adaptation therewith of the windingpinion and setting gear of a stem Winding and setting devlce inaccordance with this invention.

Fig. 3 is an enlarged sectional view illus tratmg the setting gear andwinding pinion of a stem winding and setting device in accordance withthis invention. Fig. 4 is a top plan view illustrating the setting gearof the device showing the adaptation therewlth 1n connection with one ofthe gears of a chain of gears for setting the hands. Fig. 5 1s a rearelevation illustrating the stem in an inward position. Fig.6 is a likeelevation lllustratmg the stem in an outward position.

Referring to the drawings in detail 1 denotes a pillar plate of a watchmechanism havlng connected therewith the setting gears 2, 3, for thehands.

1 denotes a pillar plate of the watch mechanism WlllCll opposes theplate 1, the latter as well as the plate 4: has the marginal portlonthereof cut away as at 5.

Secured between the plates 1, 4, is an outer supporting member 6 and aninner supportmg member 7 which are spaced from each other and the formeris positioned to extend across the openings 8 formed by the cutawayportions 5. The member 7 is arranged inwardly with respect to the cutaway portion 5 and the said members 6, 7 are secured, as at 9, to theplates 1, 4:.

The member 6 has an opening 10 through which extends a rotatable barrel11 having a squared bore 12. The outer end of the barrel 12 is flangedas at 13 and overlaps the outer face of the member 6. The inner end ofthe barrel 11 has formed integral therewith a setting gear 141 whichmeshes with the gear 2 of the chain of gearing for setting the hands.The barrel l1 continuously rotates as is obvious, that is to say whenthe watch 1s gomg.

The member 7 is provided with an opening 15 through which extends abarrel 16, the latter consisting of an inner and an outer section, andthe inner end of the outer section is toothed and engages with thetoothed outer end of the inner section. The sections are maintainedtogether by a spring 20 which bears against said inner section, thelatter is indicated at 21. The barrel 16 is provided with a pinion 18,the latter being upon the outer section of the barrel and said pinion 18is arranged inwardly with respect to the member 7 and is adapted toengage with the gearing for winding the power transmitting spring of thewatch mechanism. The barrel 16 has the outer section thereof flanged, asat 19, and the said flange engages the outer face of the member 7 and inconnection with the pinion 18 couples said outer section of the barrel16 with the member 7. The barrel 16 is provided with a square pocket 17and the latter is arranged in the inner section of the barrel 16.

The reference character 22 denotes a stem, having a squared head 23, anda reduced cylindrical portion 2 1, which carries a boss 25 to arrestoutward movement of the stem. The stem above the boss 25 is enlarged andgrooved as at 26 to receive a pair of holding springs 27. A cap 28 isconnected to the outer end of the stem and the latter is surrounded by asleeve 29, to which is connected a ring or swivel 30. The cap 28 canshift inwardly or outwardly on the outer end of the sleeve. The normalposition of the stem is such that the head 23 will seat in the pocket 17then by turning the head the squared head 23 will rotate the barrel 16and pinion 18 and under such conditions winding the power transmissionsprings of the watch mechanism. The diameter of the reduced portion 2aof the stem 22 is such that it will not engage the wall of the squaredbore 12 of the barrel 11, under such conditions the rotation of saidbarrel will not be retarded. If it be desired to set the hands the stemis pulled outward until the head 23 engages the squared bore 12 of thebarrel 11 and then by rotating the cap, the head 23 will revolve thebarrel 11, causing the setting gear 19 to be carried therewith andimparting rotation to the gears 2, 3, to set the hands.

By setting up the barrel 1G in two sections the stem can be revolvedbackwardly without revolving the outer section of the barrel whichcarries the pinion 18. hen the stem is moved forwardly to revolve thepinion 18 the teeth of the inner section of the barrel 16 will engage inthe teeth of the outer section and carry the latter therewith. When thestemis revolved backward the teeth of the section 21 will ride over the.teeth of the outer section of the barrel.
